“…Unfortunately, although a handful of bioarcheological studies examining oxygen isotope values in human dental enamel from elsewhere in the region have been recently published—including from Iron Age (800–450 BC) Germany (Oelze et al, ) and Late Viking (10th to 11th c. AD) sites in Poland, Sweden, and Denmark (Price & Frei, )—these are likely too far removed from the postmedieval period to be of great use. Conversely, the Norwegian sites of Vår Frue Kirke (AD 1500–1850), Vestfrontplassen (AD 1585–1897), and Servicebygget (AD 1585–1897) all overlapped in time with Drawsko, and when third molar enamel values were converted from δ 18 O c(VSMOW) to δ 18 O c(VPDB) (Coplen, Kendall, & Hopple, ), they produced δ 18 O c(VPDB) ranges from −8.6 to −5.8‰ with an overall mean of −7.0 ± 0.6‰ (1 σ ) (Hamre & Daux, ). Nevertheless, the physical distance between these sites and Drawsko (approximately 1,700 km), coupled with the potential introduction of conversion errors (±1.0 to 3.5‰) (Chenery, Pashley, Lamb, Sloane, & Evans, ; Pollard, Pellegrini, & Lee‐Thorp, ), makes such a comparison problematic.…”
